Thermal Expansion Characteristics11.1 The average linear coefficients of thermal expansionshall be within the limits specified in Table 4.12. Test for Thermal Expansion12.1 Heat the specimen in a hydrogen atmosphere for

24、1hat900C, followed by 15 min at 1100C. Between the 900 and1100C heat-treatment periods, the specimen may be cooled toroom temperature if desired. Cool the specimen from 1100 to200C in the hydrogen atmosphere at a rate not to exceed5C/min.12.2 Determine the thermal expansion characteristics inaccorda

25、nce with Test Method E228.NOTE 2For critical glass sealing applications, it is recommended thatthe user conduct functional testing in accordance with Practices F14, F140or F144. Such tests circumvent possible problems with thermal expansionmeasurements and glass setting point estimates.NOTE 3The the

31、ductforms.13. Transformation13.1 The temperature of the gamma-to-alpha transformationshall be below 78.5C when the material is tested in accor-dance with Section 14. However, for material whose smallestdimension is over78 in. (22.2 mm), some localizedtransformation, acceptable to the purchaser, may

32、be tolerated.NOTE 4Lower transformation temperatures, ranging to as low as196C, may be negotiated between supplier and purchaser. The 196Ctransformation temperature corresponds to immersing a sample (preparedaccording to 14.1) in liquid nitrogen for a minimum of 1 h.14. Test for Transformation14.1 C

33、ut the specimen from any part of the material, butpreferably including the entire cross section, degrease it, thenheat treat it as described in 12.1. When cool, polish the crosssection of the specimen and etch (Note 5) it in accordance withMethod E3. Then subject the specimen to the temperatureprodu

34、ced by an excess of dry ice in acetone (78.5C) for atleast 4 h. After the low-temperature treatment, examine thespecimen at a mangification of 150 for the presence of theacicular crystals characteristic of the alpha phase. Becausethese crystals may occur only in small localized areas, examinecareful

35、ly the entire polished cross section.14.2 Specimens that show no transformation and that showpartial transformation are illustrated in Fig. 1 and Fig. 2,respectively.NOTE 5A suggested etchant is a solution of three parts by volume ofconcentrated hydrochloric acid and one part of concentrated nitric

36、acidsaturated with cupric chloride (CuCl22H2O). This etchant is moreeffective when allowed to stand for 20 min after mixing. After severalhours it loses its strength and should be discarded at the end of the day.Etching is best accomplished by swabbing the specimen with cottonsoaked with the etchant

37、. Etching is usually complete when the surface ofthe metal appears to have turned dull.15. Dimensions and Permissible Variations15.1 Cold-Rolled StripCold-rolled strip shall conform tothe permissible variations in dimensions prescribed in Table 5,Table 6, and Table 7.15.2 Round Wire and RodWire and
